IMPROVEMENT lN HORSESHOMACHINES.

Specification forming part of Letters Patent No. 170,931 dated December 14, 1875; application filed November 16, 1875.

To all whom it may concern:

Be it known that I, URIAH BILLINGS, of Oambridgeport, of the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Machinery for Making Horseshoes; and do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, of which- Figure 1 is a top view, Fig. 2 a side elevation, Fig. 3 a longitudinal section, and Fig. 4 a front-end elevation, of a machine embodying my invention, which relates to mechanism for advancing and retracting the former and its carrier, and also to mechanism for operating the creasers. Figs. 5, 6, and 7 are hereinafter described. j

In the drawings, A denotes the table or frame of the machine, it being provided with ahousing, B, erected upon it, as shown, and having a horizontal slot, a, made through each of its uprights or side posts b. This housing isarranged between two toothed racks, C G, fixed to tie frame. With these racks two gears, D D, affixed on an axle or shaft, E, engage, the said ,shaft being extended through the housing or the slots thereof. To the said shaft, at its middle, there is attached the creaser-,sector F, it being the sector of a cylinder, and having projecting from its periphery the two creasers c c. The shaft E is pivoted in a slide-bar or carrier, G, to which there is also pivoted a roller, H, that is arranged inimediately over the sector F, so as to work against the cap-plate d of the housing. Underneath the said sector F is the anvil I, which extends up from the frame, and serves to support the horseshoe while being bent against the former K by the heel-benders L L, and

also while being creased and hollowed by the creasers and their sector. These benders, arranged as show-n, and provided with springs e e to open them apart, are, with the rollers M M in rear of them, shown in Fig. 5, which is a horizontal section" of the machine. Near these rollers is another horizontal .roller, N, pivoted in vibratory hangers ff. With such rollers the former K operates to bend the blank preparatory to its reception by the Hank or heel benders. This former K is projected from a slide bar or carrier, P, which is slotted lengthwise both vertically and horizontally, as shown at g and h, the driving-shaft Q of the machine being extended through the horizontal slot g, and supported in boxes t' i, arranged as represented. The carrier Gr, supported by a stationary standard, 7c, through which such carrier slides when in operation, has, at or near its rear end, a friction-roller, l, against which a cam or wiper, my, xed on the driving-shaft, operates, in order to effect the advance of the said carrier. Retraction of the carrier G is produced by the carrier P of the former K, which, during its retreat, carries abutments or projections un against studs o o, extending from the carrier G, thereby, by the action of the abutments against the studs, drawing back the said carrier. From opposi-te sides ofthe carrier P there are extended two triangular studs or horns, r r. To operate with them are two duplex cams, s s, al1 edge view of one of them being shown in Fig. 6, and an inner side view of it in Fig. 7. The projecting parts t t of such cams, during revolution of the cams, act with the studs` 1' r to impel the carrler P forward, after which they pass oi and below the studs, in order to permit the carrier to be partially thrown back by the heel-benders and their springs, which aid in effecting its retreat, the balance of its backward motion being accomplished by the duplex cams s s, two sets of toggles, T T', and two slotted levers, U U, arranged as shown. The toggles are placed underneath the duplex cams, and pivoted to the frame and the slotted levers. These latter are pivoted in turn to the frame, and receive in their slots u u projections o o from the carrier P, or a part, w, extended up therefrom. During the revolution of the duplex cams they act against the toggles, and force those of each pair' into, or nearly into, line, and thereby cause them to move the levers back. These levers in turn force the carrier backward toits rearmost position. V is the stationary cutter, and W the movable one, for separating the blank from a bar, such being as in otherhorseshoe-machines. The movable cutter is actuated by a cam, A, fixed on the driving-shaft.

In the operation of the machine, the blank, after being severed from the bar, will be driven forward, and will be partially bent by vagainst andY between theheel-benders, which will close upon it and bend it at its heels up to the former. In the meantime the machinery for operating the creasers will be inv action, whereby they Willbe caused to crease Vthe blank. All this having being done, the former K, with the blank4 upon it, will be retracted, and the blank will be discharged from it through a hole, z, in the frame.

In the said machine I claim as my invention as, follows, viz:

1. The combination, for advancing the carrier P, of the former K, and partially retracting it, such consisting of the duplex cams s s,

the projections r fr, the two pairs of toggles T T', and the slotted levers U U, all arranged and applied to the driving-shaft Q, and to the said carrier, substantially in manner as specified.

2. The combination for operating the creasers, such consisting in the vibratory sector F, its shaft E, gears D D, and racks C Cfthe carrier Gr, and its actuating-cam m,a1l arranged and applied to the housing B and the driving-shaft Q, substantially in' manner as set forth.
